# In-App Purchases with RevenueCat

### Overview <a href="#overview" id="overview"></a>

In-app purchases (IAP) refer to the ability to offer additional content or features within a mobile app for users to buy using real money. This provides a monetization strategy for app developers, allowing them to generate revenue from their apps. It's a way to offer users the option to enhance their app experience by purchasing extra items or features, such as digital goods, subscriptions, and premium content.

#### What is RevenueCat? <a href="#what-is-revenuecat" id="what-is-revenuecat"></a>

[RevenueCat](https://www.revenuecat.com/?utm_medium=referral\&utm_source=techp\&utm_campaign=thunkable\&utm_content=partner) is a platform that is used to manage in-app subscriptions and purchases. It provides tools and services to handle subscription billing, manage user entitlements, and analyze revenue data. This platform simplifies implementing and managing in-app purchases and subscriptions, making it easier for you to monetize your apps effectively.

RevenueCat allows you to start for free with everything you need to build, maintain, and grow your subscription app. Once you surpass their defined earning threshold ($2,500 USD at the time of publishing), you will be required to pay. More information is available here: [RevenueCat Pricing](https://www.revenuecat.com/pricing/?utm_medium=referral\&utm_source=techp\&utm_campaign=thunkable\&utm_content=partner).
